Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to CPython 3.9 and earlier doesn't disallow configuring an empty list ("[]") for SSLContext.set_npn_protocols() which is an invalid value for the underlying OpenSSL API when NPN is used. A remote attacker can trigger an out-of-bounds read error and perform a denial of service (DoS) attack.
